Row 1: Your answer is incorrect. • Row 2: Your answer is incorrect. Row 4: Your answer is incorrect. The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at equilibrium. You can leave out water itself. Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the formulas of the species that will act as neither acids nor bases in the 'other' row. You will find it useful to keep in mind that NH, is a weak base. 1.3 mol of HI is added to 1.0 L of a 1.3MNH, solution. 0.22 mol of HNO, is added to 1.0 1. of a solution that is 1.1M in both NH, and NH Br. ✔ acids: NH, H,O bases: 11,0, NHL, other: I acids: NH H bases: NH, other: NO, Br a S da X 0.0.

In the simulation, select the custom liquid from the dropdown list. The beaker will be filled to the 1.00 LL mark with the solution. Set the pHpH to 8.55 by entering the value in the text box provided above the pHpH scale in the panel called "pHpH." Once you adjust the pHpH, note the corresponding OH−OH− ion concentration in mol L−1mol L−1 as given in the graph on the right side of the simulation. Make sure to click the option "Concentration (mol L−1mol L−1)" under the “Water components” panel. Click on the Logarithmic scale below the graph.Find the pOHpOH of the solution.Express your answer numerically to two decimal places.
